IPC: H01M10/058
Filed: 1996-09-18
Abstract: PROBLEM TO BE SOLVED: To prevent the ignition and explosion of a secondary battery so as to make safety by installing a temperature measuring device on a lithium secondary battery, and operating, controlling, stopping the secondary battery by using a differential value in relation to the time of the measured value. SOLUTION: A temperature measuring device used a thin film temperature element of Pt-Al2 O3 , and a thermocouple of the CA type and is arranged on the surface center parts of a negative electrode plate 2 and a positive electrode plate 1 in a case 4. In regard to the time from the start of charge to the detection of a sensor in a case where the temperature is detected by the absolute value of the battery temperature and in a case where it is detected by the differential value, the time to the detection by a sensor is largely fluctuated by the holding temperature of the battery in the case of the absolute value, however, it is hardly fluctuated in the case of the differential value, regarding the case in which it is detected by the absolute value and the time from start of charging to the time when the sensor detects.  Accordingly, a detecting method by a differential value is perform detection at high precision without being affected by the outside air temperature, and it is very effective. Therefore, firing of a lithium secondary battery, to be generated caused by thermorunaway can be prevented at high precision without being affected by the outside air temperature.

Title: Etc on-vehicle machine
Inventor: SATO TERUHIRO
IPC: G07B15/00
Filed: 1998-09-01
Abstract: PROBLEM TO BE SOLVED: To prevent illegal use that an on-vehicle machine is displaced on a vehicle other than a contracted vehicle in an ETC (automatic toll receiving) system. SOLUTION: Vehicle information, etc., from an IC card for an on-vehicle machine setup is stored not in a security part 8 as in a conventional manner but in a nonvolatile memory 13 fed from a power supply part 11 using a vehicle battery as power supply. Because the vehicle information, etc., stored in the memory 13 are eliminated if the vehicle power supply of an on-vehicle machine is disconnected to mount the on-vehicle machine on another vehicle for illegal use, communication with roadside radios can not be preformed so that the illegal use can be prevented. In such a case, the setup to be made by the illegal user again is prevented by locking the ID card in an unreadable state.

Filed: 1989-09-21
Abstract: PURPOSE:To reduce space required for moving each bin for finishing treatment by setting the intervals of each bin after a sheet is extracted at a value narrower than the standby positional intervals of each bin at the time of sorting. CONSTITUTION:A sensor detects a light-shielding piece at a sheet extracting position X2 every time each bin 102 is shifted to the sheet extracting position X2, the lifting of a bin unit 101 by a moving motor M2 is stopped for a fixed time, and sheets are taken out from the upper sections of each bin 102 during the stoppage of the motor. The intervals of, the bins 102 are set at a small value in empty bins 102 in which the extraction of the sheets is completed. Consequently, height at a time when all bins 102 are lifted up to the sheet extracting position X2 is brought to a distance Hb to the standby height Ha of the bin unit 101 at the time of sorting. Accordingly, the space of an upper section required is brought to the half or less of standby height Ha.
